Tottenham crashed to their fourth defeat on the trot as Chris Powell gave Charlton their derby dozen with his first league goal for the club at White Hart Lane.

Glenn Hoddle's men, thrashed 4-0 three times in their last three matches before tonight, were denied by a string of sensational saves by the Addicks' Republic of Ireland World Cup hopeful Dean Kiely.

And - in a game watched by Sven-Goran Eriksson - England left-back Powell struck in the 70th minute to ensure Charlton's amazing unbeaten run against capital opposition stretched to 12 games.

Kiely's magnificent point-blank save from Les Ferdinand's header kept the scores blank at the interval - and the keeper made three more great saves after the break to deepen Spurs' woe.

Lady Luck is certainly not smiling on Spurs at the moment, as two Gus Poyet headers were cleared off the Charlton line - by Scott Parker and Paul Konchesky.

Hoddle had revamped his shell-shocked side for this match. Out went Dean Richards (hamstring), Teddy Sheringham (rested), Ben Thatcher (leg) and Mauricio Taricco (dropped) - and in came Anthony Gardner, Sergei Rebrov, Chris Perry and Darren Anderton (back after a hamstring problem).

For the Addicks, unbeaten in their last 11 clashes with their capital rivals in a run dating back to Boxing Day 2000, Richard Rufus returned for his first game since suffering serious knee ligament damage in August.

Gardner's tame shot in the seventh minute was the first effort at goal from either side, but it did little to perk up the home faithful, who were silent as the visiting support chanted Owe want four'.

Rufus announced his return to the football field with two thunderous fair challenges - one leaving Ferdinand in a heap and the other resulting in treatment for Gus Poyet.

The initial fizz drained out of most of the remainder of the first half, with Spurs - not surprisingly - appearing somewhat disjointed after three crushing defeats.

Kiely made a sensational fingertip save from easily the best opening of the match in the 32nd minute.

Christian Ziege looped over a curling cross from the left flank and Ferdinand stooped to head the ball powerfully goalwards from just seven yards out.

However, Kiely stretched out his right hand and got just enough contact to deflect the ball away from his net.

However, Charlton were still threatening and Mathias Svensson awkwardly headed behind from Parker's excellent ball into the box.

Sullivan also made a smart block after Parker put Young in on goal - and from the resulting corner, Jorge Costa looped the ball onto the roof of the Spurs net.

At the other end, Parker cleared off the Charlton line from Poyet's header on the stroke of half-time.

After the interval, Kiely really came into his own. He had to be alert to gather a well-hit Rebrov drive in the 58th minute - and then made a save even better than his first-half block from Ferdinand's header.

Davies picked out Poyet with a superb diagonal ball - and when he shot, the Addicks number one just clipped the ball round the post.

Kiely was also in action again moments later when he stuck out his left boot to keep out Poyet's 12-yard effort.

But it was Charlton who took a shock lead as the clock ticked past the 70-minute mark, with a goal that will give Hoddle nightmares.

Addicks captain Graham Stuart crossed from the right, and as the ball looped over Euell, Ledley King made a hash of his clearance.

The Tottenham defender succeeded only in kneeing the ball into space - and left-back Chris Powell stole in to grab his first league goal for Charlton, bundling the ball home from close range with the outside of his right thigh.

The England defender's only other goal in four years at The Valley was ironically also against Tottenham, in Spurs' 4-2 FA Cup fourth-round victory last season.

Charlton had to cling on by the skin of their teeth with two minutes left.

Poyet's powerful header from Ziege's corner was first headed onto the underside of his crossbar by Charlton substitute Konchesky - who then cleared the rebound.
